LOUIS STRICKEL, OF DETROIT, MICHIGAN, ASSIGNOR OF ONE-HALF TO GEORGE C.WETHERBEE, OF SAME PLACE.

BRUSH-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 412,305, dated October8, 1889.

Application filed March-2, 1889. Serial No. 801,7 72. (No model.)

To aZZ whom it may concern.-

Be it known that I, LOUIS STRIOKEL, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan,have invented acertain new and useful Improvement in Brush-Nailing Machines; andIdeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to whichitappertains to make and use the same, reference being had to theaccompanying drawings,which form a part of this specification.

My invention has for its object a new and useful improvement inbrush-nailing machines, whereby such a machine shall be adapted fordriving the nails into the middle of the brush-head to hold in place thestock engaged in the middle of the head, as more fully hereinafterdescribed and claimed and more fully illustrated in the acccompanyingdrawings, in which Figure 1 is a plan view embodying my invention. Fig.2 is a front elevation of the nail-bars and the supporting-head. Fig. 3is a vertical section on the line a; 00, Fig. 1. Fig. 4 is a verticalsection of features of my invention on the line y y, Fig. 1, showing therelation of parts when the nails have been driven home. Fig. 5 is a viewin perspective of one of the bracketarms; and Fig. 6 is a View similarto Fig. 4, but showing the relation of parts when ready for thereception of the brush to be nailed.

The more specific purpose of my present invention is to provide anailing-machine adapted for the manufacture of my improved brush, forwhich an application for Letters Patent was filed by me August 24, 1888,Serial No. 283,607.

It will be understood that the brush-head A (shown in Fig. 4.) isconstructed with longitudinal grooves, as at o. a 0. for the receptionof the stock A, which is bent over a binding-wire a extendinglongitudinally of said grooves, and which in turn is held firmly inplace by a series of nails driven into the brush-head adjacent to saidwire and in such a manner as to retain the binding-wire in place. A nailso driven is shown in Fig. 4 at a. It willv be obvious that the nailsholding the binding'wires in the middle grooves of the brush-heads mustbe driven into the head on a slant, there being no opportunity to drivethe nails in any other direction, while the nails to hold thebinding-wires in the marginal grooves may be driven straight into thehead from the side.

B B represent the guides into which the stock is forced and over it thebinding-wire,

and B is a suitable plate employed to force the stock and wire into thebrush-head. The

stock is forced into the guides by an attendant on a separate machine,the plate B being driven to the base of the guides, in which conditionthe guides, with stock and plate thus engaged therein, are passed to thenailing-machine.

I will now proceed to describe the nailingmachine and its operation.

G represents any suitable supporting frame or bed.

D D represent adjustable brackets to em brace the ends of the brush headand guides. For longer or shorter brushes these brackets may be moved toand fro, as required.

E is a movable head-block adjusted by means of an operating-screw E,adapted to be brought against the side ofv the brush-head to brace thehead when the nails are driven thereinto.

F represents a vertically-oscillating arm having a jointed engagement atits rear extremity upon the frame, as shown at c. Said arm is providedat its forward extremity with a supporting-head F, constructed to engagethe plate B To this end the head is shown in this instance as providedwith supporting studs or posts h to engage similar apertures in theplate, as shown in Fig. i at h. A bar 1) above said studs is calculatedto bear upon the plate to press the stock into the groove of thebrush-head.

To oscillate the arm Fa foot-lever G is shown in this instance assuitably connected therewith, as by the connecting-bar G. The arm ismade self-retracting in any desired manner, as by a spring G H is anail-bar constructed to receive a desired number of nails. To this endit is constructed with a suitable nu nber of orifices, as at h' h, intowhich individual nails maybe located ready for driving. This nail-bar isI bring the nail-bar into proper position. The

wires h h are simply looped over the upper end of the bolt H, as shown.By removing said bolt the nail-bar and the spring H may very readily beremoved altogether from the machine when desired. Being connected withthe oscillating arm, it is evident that the nail-bar will movevertically therewith as the foot-lever G is operated When in place fordriving the nails, as shown in Fig. 4, it is manifestly impracticable toinsert the nails into the nail-bar or to engage the clamps and plate Bin place over the brush-head; but by allowing the supporting-head andnail-bar to be lifted into the position shown in Fig. 6 this work may beconveniently accomplished.

I is astationary nail-bar provided with orifices t' to receive thenails. The orifices t'may be horizontal, as this stationary nail-bar isused for nailing through the margins of the brush-head. It may beadjusted for various sizes of brush-heads by means of screws 1 I asheretofore common.

J denotes a rocking driving-bar provided with driving-fingers j, engagedupon said bar, as by means of a collar j, said fingers proj ecting intothe adjacent orifices of the nail bar H. This driving-bar is engaged atits extremities in supporting-brackets K K, engaged upon the frame orbed 0, said brackets being constructed with a downwardly-inclinedelongated slot to receive the drivingbar when the nails are to be driveninto the middle of the brush, and preferably also with horizontalelongated slots 70 to receive the driving-bar when the nails are to bedriven straight into the margin. of-the brush-head.

L is an operating-lever engaged with the driving-bar, as byconnecting-bars ll, saidlever having a jointed engagement on said bed,as shown at Z By this construction it is apparent that the operatorbyseizing said lever and pulling it forward will force the driving-fingersupon the nails in the nail-bar and simultaneously drive them into thebrush-head.

The operation of the device will now be understood. The operator locatesa brushhead upon the bed between the brackets D D. The machinery beingin readiness for nailing the stock into the middle groove, the operatorbrings the guides B B, with the stock and plate B engaged therein, intoposition, engaging the plate upon the studs b. The

nail-bar having been filled with nails,the operator applies his foot tothe foot-lever, there by forcing the plate B firmly,'withthe stock andbinding-wire a into the middle groove. At the same time the nail-bar His brought into proper position for nailing. The operator then seizesthe lever L and thrusts it forward, driving the nails into thebrushhead. The foot being released from the lever G, the lever F, withits connected parts, is restored to normal position. It is customary tonail the stock into the middle grooves of the head in a large number ofheads, one after another. Then by removing the nail-bar H thedriving-fingers are engaged in the nailbar I and the driving-bar in theslots-.10 of the brackets K K, when the machine is ready for driving thenails into the margins of the heads. The nails in the middle having tobe driven on a slant, the orifices in the nail-bar H are also run in aslanting direction.

The spring H serves to hold the adjacent nail-bar firmly in place whilethe nails are driven into the brush-head.

It will be observed that the nail-driving bar J is supported in thebrackets K K independently of the operating-lever L, the latter simplyserving to actuate the driving-bar.

What I claim as my invention is- 1. In a brush-nailing machine, thecombination, with a supporting-frame, of the movable arm F, having anail-bar engaged therewith, and a driving-bar, substantially as setforth.

2. In a brush-nailing machine,.the combination, with a supporting bed orframe, of a movable arm F, having a nail-bar H e11 gaged therewith, adriving-bar, and operat ing-lever, said bar mounted in brackets K K,said nail-bar and brackets constructed with inclined recesses and slots,respectively, substantially as set forth.

3. In a brush-nailing machine, the combination, with a supporting bed orframe, of a movable arm F, having a nail-bar engaged therewith, adriving-bar, and means for reciprocating said bar, said nail-barprovided with a spring H substantially as set forth.
